Specification of Letters Patent.

Patented Aug. 23, 1910 Application filed August 26, 1908. Serial No. 450,263.

One object of the inventionis to provide an improved mechanism that ,will successively feed and force the heads or ends onto the body.

Another object is to provide an improved construction whereby a single mechanism will force one head onto a .body while it is feeding other heads for other bodies.

A further object is to provide a construction that will simultaneously feed a-plurality of heads or ends in a directline or at right angles with respect to the open ends of the bodies.

Another object of the invention is to provide an improved mechanism that will enable the heads or ends to be piled or placed in a chute in a horizontal position,one head or end above another and to separate said heads or ends and force them successively onto the bodies.

A still further object is to provide an improved mechanism that will receive a plurality of heads or ends piled one on top of the other in a horizontal plane and to lower the pile of heads or ends and deliver them successively at the open end of the body and to force said head or end onto the body.

Another object is to provide a screw mechanism that will sustain the heads or ends circumferentially and convey them while thus sustained to the open end of the body.

Other objects and advantages arising as the, result of the invention will be hereinafter described and made the subject of the appended claims.

The invention is illustrated in the accompanying drawings, in which, I

Figure 1 shows a side elevation of the im roved machine. Fig. 2, a plan view of the same. Fig. 5, is a central vertical section thereof, and Fig. 4, is a horizontal cross section of the macbine,the section being 6;, may travel beneath the top so as to pret-aken on the line H of Fig. 3. Fig. 5 is a sectionaldetail of a top and can and shows the relation they have to each other as they are brought together.

In the drawings the numeral, 1, designates a base of any suitable form but in the presentinstahce comprising the sides, 2, and, top, 3. In its present form the base has a bottom flange, 4, by means of which it may be secured in place, and it is also preferably de signed with an opening at opposite sides that it may be bolted down on a suitable bed withits: side walls, 2, spaced apart-in order that a conveyer, 5, having suitable can seats,

sent the can-bodies, 7, successivelyto receive the heads or ends.

By reference to Fig. 2 it will'be clearly seen that the top, 3, is provided with an' opening, 8, into which the lower-end of a 7.5

tubular shell, 9, which serves as a chute, is

fitted. The shape of this opening and shell depends entirely upon the shape of thehead to be applied and whilein the present instance the opening and shell are circular it is obvious that the shape of the same may be varied.

On the inner or under side of the head I sustain a plurality of screws, 10, which have position so that their threaded circumferential edges will project slightly across the plane of the. opening,'8, in the top of the base. In practice I have found that three screws are sufiicient to properly carry out the function for which they are employed but it is to be understoodthat the number of screws employed is immaterial and may be varied; Thesescrews are sustained on vertical shafts, 11, which extend through and have bearing in the top, and above said top each shaft is provided with a sprocket wheel, 12. A sprocket chain, 13, passes. around and engages all the sprockets so that when the chain is driven in a horizontal plane the sprockets and screws will be revolved at opposite sides of the top.

At one side of the top I mount a slotted plate, 14, which carries an idler wheel, 15, at one end and this plate is adjustably secured on the top by means of a bolt, 161 The idler wheel, 15, engages the sprocket chain and serves to take up or adjust the slack in the chain merely by shifting the slotted plate on the top. In order'to drive the chain and thereby a pinion, 18, on the inner end of a horizontal shaft, l9,'me'shes. This horizontal shaft may be. driven in any suitable manner.

In practice the heads or ends, 20, to be applied to the bodies are first piled or deposited in the tubular shell with their bottom sides facing toward the screws so that the screws will serve as a support for the column of heads or ends.

The heads or ends are circumferentially engaged by the screws which maintain and convey them in a plane parallel with the length of and toward the body.

The bodies are placed on the conveyer, 5, and carried beneath and centered with respect to the screws, and the revolution of the screws causes the heads or ends to be fed toward and forced onto the centered bodies one after another.

It will be noted, by reference to Fig. 5

that the can bodies are provided with a horizontal rim flange, 21, while the top is provided with an annular groove or channel,

22, with a slight depending rim-flange, 23. When the top is forced down onto the body the flange, 21, of the body will fit into the groove or channel, 22, of the top and the body with the top attached is then conveyed to a seaming head or tool which curls or rolls the flanges, 21, and, 23, into a lock seam.

It will be'seen that while one head or end is being forced onto a body other heads or ends are traveling toward the ends of the screws.

The revolution of the screws effects a continuous feeding of the heads or ends while the bodies are fed intermittently so that they will be centered successively.

It is obvious that the term head or end as used herein means one and the same thing and whenever either expression is employed it is to be construed as covering either the top or bottom of the can as obviously the ma' chine will apply the bottom heads as readily as the top heads.

Having thus described my invention what I claim and desire to secure by Letters Patent is,-

1. A body-heading machine comprising an intermittently traveling body support, a head support, and means for continuously conveying heads from the head support toward the intermittently traveling support. 2. A body-heading machine comprising an intermittently traveling body support, a head support, and a plurality of screws operating continuously in a plane between the head support and the traveling support.

3. The combination with a body support,

of a plate sustained above the body support and having an opening therein; means for assess delivering heads to said opening, and a plurality of screws sustained at the under side of the plate and around said opening whereby to receive the heads passing through the opening.

4. The combination with a body support, of a plate sustained above the body support and havin an opening therein, a plurality of vertica shafts extending through the plate and positioned around said opening, screws on saidshafts at the under side of the plate, and means on said shafts at the upper side of the plate for'revolving said screws.

5.
